Technical Reference Manual

INTRODUCTION

Behind the features described in the Operating Manuals lies the operating system and hardware.

This document was compiled from various sources to give a complete description of how the operating system and hardware work together. It covers all base models - CM, XP, LZ - and their POS variants. The intended audience are machine code programmers and hardware developers. If you are looking for general information, see the manuals page first!

If you are able to supply additional information, or for reporting an error please mail to Boris Cornet.
